#2 - Drew McIntyre
Drew McIntyre has had a helluva run ever since his arrival on the main roster. An unused talent who worked for different wrestling promotions arrived in NXT and Monday Night RAW in 2018.
Reports mentioned that the company was high on McIntyre in 2019 and has huge plans for him. It could be a possibility for Drew McIntyre to achieve the top card following the absence of Roman Reigns due to leukemia.
WWE decided to align Drew McIntyre along with Dolph Ziggler in his first appearance after many years. The 'Shawn Micheals - Diesel' sort of alignment focused on pushing Drew's character as a dominant force.
As the run with Dolph ended recently, there is a possibility of a push after his feud ends with both Finn Bálor and Dolph Ziggler.
As Braun Strowman is prepared to face Brock Lesnar for the Universal Championship, there might be a title change with Strowman winning the title and then, Drew winning the Royal Rumble match.
